NASA's Juno mission has revealed that Jupiter's core is "fuzzy," challenging theories of planetary formation. The probe also captured stunning images of polar cyclones, analyzed atmospheric composition, and provided new insights into Jupiter's powerful magnetic field and auroras.
The day of equal daylight and darkness, known as the equilux, typically occurs a few days before the spring equinox. This difference is due to Earth's atmosphere bending sunlight, making days appear longer.
The Vera C. Rubin Observatory is now live, transmitting a massive stream of astronomical data that's accessible to everyone. Sophisticated data brokers and filtering tools allow astronomers and citizen scientists to search for new cosmic events in near real-time, promising a new era of discovery.
A groundbreaking proposal envisions a 99-meter starshade orbiting Earth, capable of blocking starlight to reveal exoplanets for powerful ground-based telescopes. Meanwhile, new analysis of the DART mission's final moments offers visual proof of asteroid moon formation, and cosmic tension persists as scientists refine the age of the universe.
Astronomers, astrophysicists, and cosmologists employ diverse methods to study the universe, from observing distant galaxies to understanding cosmic origins. Access to powerful telescopes like JWST is competitive, requiring strong scientific proposals. Neutrinos offer early warnings for supernovae, while planetary gravity poses a significant challenge for space exploration.
A simple shadow illusion reveals the Sun's true shape, demonstrating the pinhole camera effect. This everyday phenomenon confirms the Sun is round, regardless of the aperture's shape, by projecting a perfect circle of light.
The Vera C. Rubin Observatory has begun its mission to map the southern sky, making it the most promising tool yet to discover the hypothetical Planet Nine. The observatory is also shedding light on exoplanet detection and the science behind telescope interferometry and galaxy imaging.
The Habitable Worlds Observatory, designed with input from JWST's architect, aims to directly image Earth-sized exoplanets and analyze their atmospheres. The James Webb Space Telescope continues to exceed expectations, offering hope for extended operational life and groundbreaking science.
The James Webb Space Telescope has detected significant amounts of water vapor in a galaxy located 12.5 billion light-years away. This discovery provides crucial insights into the conditions of the early universe and the prevalence of water, a key ingredient for life.
For ten years, questions about black holes have dominated public curiosity. A new 10-hour compilation reveals fascinating insights into their formation, behavior, and cosmic role, from stellar remnants to galactic centers.
